"稻-虾-螺"复合种养模式对稻田产量与经济效益的影响
Effects of the co-culture model of rice-prawn-river snail on the yield and economic benefits of paddy fields
摘要
Abstract
[Objectives]The effects of the co-culture model of"rice-giant freshwater prawn-river snail"on the output and comprehensive economic benefits of paddy fields were studied to provide a reference for eco-friendly and high-value utilization of paddy fields.[Methods]Field experiments were conducted in Liuzhou City,Guangxi Zhuang Autonomous Region from 2021 to 2022.Two groups including the experimental group(the co-culture system of rice-giant freshwater prawn-river snail)and the control group(rice monoculture)were set up to measure the yield and value of rice,prawns and river snails and analyze the driving characteristics of its eco-nomic benefits with principal component analysis(PCA).[Results]The experimental group increased the output of aquatic products on the basis of an average rice output value of 1 449.54 yuan/667 m²,with a comprehensive profit of 1 775.15-7 323.60 yuan/667 m² and an input-output ratio of(1∶1.29)-(1∶2.18).All economic in-dexes were higher than those of the control group.The higher initial investment into the experimental group ef-fectively converted into high-value output of benthic organisms,driving its comprehensive benefits to be better than the control group.[Conclusions]The co-culture model of rice-prawn-river snail can effectively improve the economic benefits of paddy fields.It not only has a strong ability to resist risk but also provides a localized solu-tion of river snails as raw material for the Luosifen industry,which is an ecological and high-value utilization model of paddy fields worthy of promotion.关键词
